Thanks for your reply Kevin :) I just noticed that a new bios is out, version 2.25 dated 29. May. I'll give this new bios a try and also update current and make world. If there is no change, I'll stick with APM. regards Marcin Kot ----- Original Message ----- From: "Kevin Oberman" <oberman@es.net> To: "Marcin Kot" <mailingliste@broadpark.no> Cc: <freebsd-mobile@freebsd.org> Sent: Thursday, May 29, 2003 5:10 PM Subject: Re: 5.1b2, configuring kernel for Thinkpad x20 > > From: "Marcin Kot" <mailingliste@broadpark.no> > > Date: Thu, 29 May 2003 16:35:10 +0200 > > Sender: owner-freebsd-mobile@freebsd.org > > > > Hi, > > > > I have a Thinkpad x20 which is running 5.1-BETA2.
